1 SECTION FOUR Operational Amplifiers: Temperature-Controlled Fan 2006 Oregon State University ECE 322 Manual Page 45
2 SECTION OVERVIEW In this section, you will resume the task of building your power supply. Use your knowledge of operational amplifiers (Op- Amps), to construct a circuit that will control the speed of a cooling fan based on temperature. Objectives Design a circuit with an operational amplifier The op amp controls the speed of the fan, based on the temperature inside the power supply case. Materials Your lab kit and power supply. Test leads and oscilloscope probes. Design Constraints Box 4 lists some of the design constraints for the fan controller. The best source for these constraints is the Project Specification Document. Keep these in mind as you complete each section of this lab. Each criterion must be met. PRE-LAB Safely equipped with a cooling fan that should not normally be running at 70 F, but should still be able to reach rated speed around 95 F. Design should use an op-amp, and a BJT (or MOSFET) to control the fan speed. Assembled safely and with no electrical hazards. Box 4: Fan controller design constraints For the Pre-lab for Section Four, complete the following: 1. Using SPICE, design and simulate a circuit that will control the speed of a fan based on temperature. (You can model the fan as a resistor, but choose the resistor value carefully). Refer to your notes from Electrical Fundamentals I (ENGR 201), if you have forgotten how to use an Op-Amp or your own notes from this course. For more information about the thermistor and the fan in your kits, you may want to visit the supplier Web-site and check the datasheets for the components. If this is not sufficient, perform experiments to verify the values of the components. Hint: Double-check the current needed for the fan, and make sure your circuit can handle it. Page 46 ECE 322 Manual 2009 Oregon State University
3 2. Bring a printed copy of the datasheets for the parts used in this lab. These should include the datasheets for the LM/UA 741 (or some other op-amp), the thermistor, and any transistors that you may use in this lab. LAB There is only one part/ task for the lab portion in Section Four, which is the fan controller. In order to design and build a circuit that automatically varies the cooling fan speed, based on the input from a thermistor, follow these steps: 1. Build your design on solder-less breadboard. 2. Test your design. The fan should turn slowly, or not at all, when the temperature sensor is cool (about F). The thermistor you will be using is of type NTC (Negative Temperature Coefficient). This means that the resistance of the thermistor lowers as the temperature rises. 3. About the voltage: The voltage on the fan is about 11-12V when the sensor is warm, (i.e. at about F). Do not forget that the fan represents a load, and therefore needs to be included while designing. 4. Verify the operation: Verify these operating points, by comparing the fan speed at room temperature, and while the sensor is being pinched between warm fingers. 5. Add the controller to your power supply. Carefully consider the sensor and fan placements in order to obtain the best cooling and most accurate measurement of temperature. 6. Demonstrate your working design to the TA. Power supplies can be cooled passively, (i.e. without a fan). This type of design would require you to mount the TIP29/ TIP30 transistors to the case. Another consideration with this design is that the part of the case to which you mount your transistor, must have numerous cooling fins Oregon State University ECE 322 Manual Page 47
4 TURN-IN The following need to be turned in, at the beginning of the next lab (Section Five). Student Name: Lab Section Time: Test (from Project Specification) Measurements TA Signature THERMAL PROTECTION BLOCK - FUNCTIONAL COOLING FAN THERMAL PROTECTION BLOCK - DESIGN SHOULD USE AN OPAMP AND A BJT OR MOSFET TO CONTROL THE FAN THERMAL PROTECTION BLOCK - THE FAN AND ITS CONTROL CIRCUIT ARE ASSEMBLED SAFELY AND WITH NO ELECTRICAL HAZARDS The written project specification to be turned in next week includes: Project Specification Sections for this lab s circuits: Block Diagram Interface Definition Schematic and theory of operations Parts List Changes and Testing Results The prelab to be completed (before lab begins next week), includes: Prelab for Section Five. Lastly, turn in your answers to the study questions below. 1. Write a description of the type of circuit that you have built. Include a discussion of whether it has positive or negative feedback, is inverting or non-inverting, and about the gain. Explain why you chose this design and how it works. Page 48 ECE 322 Manual 2009 Oregon State University
5 2. Does the current flowing through your thermistor cause it to heat up? How much power are you dissipating in the thermistor? Explain why you do or do not consider this power dissipation to be a problem Oregon State University ECE 322 Manual Page 49
6 CHALLENGES 1. Modify the fan controller to have hysteresis, thereby causing the fan to continue running until the temperature has fallen below that value, (which caused the fan to turn on). For this design, your fan should actually turn off when cool, rather than just slowing down. 2. Mount your fan in a way that either increases performance, reduces noise, looks cool, or all of the above. Make sure that your fan modification is safe and does not expose any blades.
